In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. The distribution is named after Lord Rayleigh . A Rayleigh distribution is often … See more The probability density function of the Rayleigh distribution is $${\displaystyle f(x;\sigma )={\frac {x}{\sigma ^{2}}}e^{-x^{2}/(2\sigma ^{2})},\quad x\geq 0,}$$ where See more Consider the two-dimensional vector $${\displaystyle Y=(U,V)}$$ which has components that are bivariate normally distributed, centered at zero, and independent. Then $${\displaystyle U}$$ and $${\displaystyle V}$$ have density functions See more • $${\displaystyle R\sim \mathrm {Rayleigh} (\sigma )}$$ is Rayleigh distributed if $${\displaystyle R={\sqrt {X^{2}+Y^{2}}}}$$, where $${\displaystyle X\sim N(0,\sigma ^{2})}$$ and $${\displaystyle Y\sim N(0,\sigma ^{2})}$$ are independent See more • Circular error probable • Rayleigh fading • Rayleigh mixture distribution • Rice distribution See more The raw moments are given by: $${\displaystyle \mu _{j}=\sigma ^{j}2^{j/2}\,\Gamma \left(1+{\frac {j}{2}}\right),}$$ where See more Given a random variate U drawn from the uniform distribution in the interval (0, 1), then the variate $${\displaystyle X=\sigma {\sqrt {-2\ln U}}\,}$$ See more An application of the estimation of σ can be found in magnetic resonance imaging (MRI).

WebMay 16, 2024 · Since the Q function is the tail of a Gaussian distribution, BER of QPSK in AWGN is found using SNR and the Q function. Rayleigh distribution can be thought of as a complex valued AWGN. One of the easiest ways to derive Rayleigh is to start with two AWGN PDFs that are orthogonal. So I'm pretty sure you just use the SNR and the CDF …

The Rayleigh number describes the behaviour of fluids (such as water or air) when the mass density of the fluid is non-uniform. The mass density differences are usually caused by temperature differences. Typically a fluid expands and becomes less dense as it is heated. Gravity causes denser parts of the fluid to sink, which is called convection. Lord Rayleigh studied the case of Rayleigh-Bénard convection. When the Rayleigh number, Ra, is below a critical value for a fluid… WebDetails.
